Why do I have these weird reflections?
Just posting this so I can post the pic. I suspect the problem is that you have your light radius set too large. It's hard to tell from the video, but it looks like you have a point light above your &quot;room&quot;. As you can see from the image below, a large light bleeds through the walls and reflects off the roof similarly to how it does in your video. If you have a point light with a radius that is large, consider reducing the size. If you don't want it coming through the walls, also consider enabling contact shadows, but bear in mind, this may require your walls to have some thickness to work properly. See below:
